Quartz (qz.com).

It runs off WordPress, but the entire front end is abstracted into a JavaScript web app that is optimised for the user reading content without having to think. HTML5 allows it to deliver the unique experience of endless article scrolls in sync with side navigation that can be used offline.
 
4) Which features stand out particularly in terms of best-practice?
The site is completely API driven so front end is its own JavaScript web app. It is a simple concept with everything executed well and about two years ahead of everyone else with regards to thoughts and approach.

You can browse a large set of articles offline after reading just one, due to the JSON [JavaScript Object Notation] being stored locally on the device.

Infinite scroll always gives the user something else to browse onto and engage without making them think or putting a load of rubbish in the way.

Yes, Quartz has grown to 5 to 8 million unique visitors a month and delivers good revenues due to their targeting of a well-paid demographic.
 
8) Is there anything that you would have done differently? Or would suggest that this site might do to improve the site further in the future?
No.

9) What other tips can you offer companies that are considering HTML5 development?
Less is more when it comes to what you are trying to achieve – it’s much better to do a few things really well than a lot of things half baked. Work within the constraints of the web; as people are used to how the Web works and have embraced its constraints.
